Thrash is the dragon mount of Milia, the second in command of the Dragon Knights. When Windy poisoned the other dragons Milia and Thrash were away on a mission and so were unaffected. As a result Thrash was used to convey the Tir, Flik, Milia and Humphrey to Seek Valley in search of the Moonlight Weed. After the Dragon Knights joined the Liberation Army, Thrash's ice breath was used to help create a flotilla of ice boats to attack the Fortress of Shasarazade. - Blue Moon
